Developmental anomalies of the aortic arch, commonly known as vascular rings, are relatively rare congenital vascular anomalies which can compress the trachea and esophagus. We have presented six patients with surgically treated vascular rings at Seoul National University Hospital during the period June 1970 through May 1984. Two patients had double aortic arches and four patients had right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum. Four patients had symptoms relating vascular ring and two patients were detected incidentally during diagnostic evaluation of symptomatic intracardiac defects. Associated congenital malformations were seen in four patients. The operative approach was through left thoracotomy in three patients and median sternotomy in remaining three patients associated with congenital cardiac defects. There were no postoperative deaths with excellent result in preoperative symptomatic patients. To our knowledge, successful surgical repair of vascular ring has been reported only once in the Korean literature.

The results of the clinical observations on the bronchogenic carcinoma of forty-five cases treated in the Department of Thoracic and Cardiovascular Surgery, Chungnam National University Hospital, during the period of 6 years from June.1978 to Aug. 1984, are as follows: 1. Of 45 cases, 44 cases were over 40 years of age and the sex ratio was 4.6:1 in male`s favor. 3. Among 50 cases, 45 cases were confirmed histopathologically. Of these, 30 cases [66.7%] were squamous cell carcinoma, 8 cases [17.8%] adenocarcinoma, and 7 cases [15.6%] undifferentiated cell carcinoma. 4. The thoracotomy was performed in 31 cases [68.9%] of 45 cases and the resection of the lesion in 16 cases [51.6%]. The empyema and bronchopleural fistula developed in 2 cases.

A clinical evaluation was performed on 811 cases of chest trauma who were admitted and treated at the department of thoracic & cardiovascular surgery, Catholic Medical College, during the past 19 years from Jan. 1966 to Dec. 1984. 1. The overall incidence rate of male to female was 3:1. 2. The common age groups were 4th, 5th, and 3rd decades. 3. The most common cause of chest trauma was stab in penetrating wound and traffic accidents in non penetrating wound. 4. The most common injury from non penetrating chest trauma was rib fracture [81.3%], and the incidence rate of flail chest was 14.5% of all cases of rib fractures. 5. The incidence rate of hemo-pneumothorax was 50.4% in non penetrating wounds, and 55.2% in penetrating wounds. 6. The most common method of surgical treatment was CTD [33.5%], and open thoracotomy was performed in 67 cases [8.3%]. 7, The overall mortality was 3.3% [27 cases], and common causes of the death were shock and respiratory insufficiency.

Twenty-three patients with traumatic diaphragmatic injuries treated at the Department of Thoracic and Cardiovascular Surgery, Keimyung University Dongsan Medical Center from Aug. 1978 to Nov. 1990 were reviewed. There were 19 male and 4 female patients. The age distribution was ranged from 1.5 to 72 years, with a mean age of 34.3 years. Sixteen patients had blunt trauma[traffic accident 14, fall down 2], and 7 had penetrating injuries[stab wound 6, broken glass 1]. Sixteen [70 percent]of the injuries occurred on the left side and 7[30 percent] on the right side. Fifteen patients were operated on during the acute phase, 5 patients during the latent phase, 2 patients during the obstructive phase. The surgical approach in 20 patients was through a thoracotomy; in 2 patients, a thoracoabdominal incision was necessary, and in 1 patient, a laparotomy was performed. Herniated organs in thorax included stomach[10], colon[5], small bowel[5], spleen[4], liver[2]. Postoperative complications included wound infection, empyema, pneumonia, hepatitis and respiratory failure. There were 3 postoperative deaths, 2 with cerebral dysfunction and 1 with sepsis.

Neurogenic tumors of the mediastinum may have an intraspinal component connected by a narrowed segment of tumor in the intervertebral foramen, then have symptoms of back pain,lower extremity tingling sensation. CT scan or MRI demonstrated a Dumbbell-shaped mass density compressing spinal canal, enlargement of the foramen, erosion of bone, and intervertebral widening. We report the analysis of the 18 cases of neurogenic tumors on posterior mediastinum and Dumbbell type tumors are 3 cases among the 18 cases. The neurilemmomas were 12 cases[67%], the ganglioneuroma were 5 cases[28%], and neuroblastoma was one case[5%]. The successful removal was done in all cases, a standard thoracotomy and laminectomy was done in Dumbbell type tumors.There was no postoperative neurological complications.

Eight surgically treated patients with leiomyoma of the esophagus are presented. The patients were 6 men and 2 women whose ages ranged from 20 to 50 years. One of them was asymptomatic, while the remaining seven had mainly dysphagia and weight loss. The preoperative diagnosis was made in 6 cases. One patient had coexisting esophageal carcinoma masking the presence of the leiomyoma and masking the lesion an incidental operative funding. The other which was asymptomatic was diagnosed as a mediastinal tumor preoperatively. Six patients were treated by thoracotomy and enucleation of the tumor. Two patients were treated as esophagectomy and esophagogastrostomy. There were no operative deaths, and the overall results were excellent.

We experienced a case of esophageal leiomyoma recently in department of Thoracic and Cardiovascular Surg., Pusan Baik Hospital, Inje Medical College. Patient had suffered from dysphagia and chest discomfort for 2 years. The esophagogram showed an ovoid smooth filling defect in lower portion of the esophagus, mucosal fold of esophagus was not destroyed. A benign intramural tumor of the esophagus such as leiomyoma was suspected with X-ray finding and clinical features. Open thoracotomy was performed through the left 8th intercostal space. A firm egg sized mass in the well of lower esophagus was enucleated by blunt dissection with caution to avoid injury of the mucosa of the esophagus. The diagnosis of leiomyoma was confirmed with histopathological finding. Postoperative course was uneventful.

Surgical approaches were performed with thoracotomy in 9 cases, median sternotomy in 3 cases and direct incision above the wound. 5. Sites of injury were heart in 10 cases and great vessel in 7 cases. The right ventricular injury was most common as 7 cases. 6. Operative procedures were performed with simple closure, vascular graft anastomosis and ligation. There was no postoperative death.

; A 15 years old girl was operated due to tuberculous paratracheal lymph node enlargement resulted in marked narrowing of lower part of trachea. She had suffered from sputum expectoration difficulty, which was developed dyspnea and cyanosis. 1st operation was simple removal of enlarged paratracheal lymph node through Rt. thoracotomy but restenosis sign developed 2 months later in spite of Anti-Tbc. medication. 2nd operation was resection of constricted tracheal portion [2.5cm] 8 end to end anastomosis under Extra Corporeal Circulation. Under Extra Corporeal Circulation trachea reconstruction offered many conveniences during operation. Till now, she has been follow up checked for one year, she was very good post-operation state without any restenosis signs.

Recently, we experienced a case of rare neurilemmoma originated from intercostal nerve [9th] in the right chest wall in a 25 year old male officer. The tumor was incidentally found in the routine chest X ray, where the round well circumscribed mass tumor the ninth rib with notching and sclerotic margin, suggesting slowly growing benign benign of chest wall was revealed and the tumor mass was easily extirpated in the exploratory thoracotomy, with uneventful recovery. Grossly, the tumor was firm, partly soft and well circumscribed, measuring 4.5X3.0X 3.0 cm with yellowish smooth outer surface, attached with intercostal nerve trunk. Cut surface exhibits partly grayish white and largely hemorrhagic areas. Microscopically, the characteristic palisading arrangement of schwann cells and Verocay bodies are seen but dominant features are cystic degeneration and hemorrhage with organization and fibrosis. The sheath of intercostal nerve and capsule of neurilemmoma were con joined. There is no evidence of malignancy. The tumor was confirmed as neurilemmoma of intercostal nerve, Antony type B.
